Zinc Metal Wire for Thermal Spraying
High purity zinc metal wire designed to improve corrosion resistance and extend service life of steel structures through thermal spraying applications.
Product Overview
Zinc metal wire is a high purity coating material widely used in thermal spraying applications to improve corrosion resistance and extend the service life of steel structures. Through arc spraying or flame spraying processes, zinc wire is melted and deposited onto steel surfaces to form a protective zinc coating layer.
The zinc coating provides long-term protection through two mechanisms: barrier protection and sacrificial cathodic protection. It prevents direct exposure of steel substrates to moisture, oxygen and corrosive environments while zinc acts as a sacrificial material to protect the underlying metal.
Zinc metal wire is widely applied in bridges, pipelines, offshore structures, storage tanks, industrial equipment and other steel structures requiring durable corrosion protection.

High purity composition helps achieve stable melting performance and uniform coating quality during thermal spraying.
Protection Mechanism
During thermal spraying, zinc wire is melted and sprayed onto prepared steel surfaces. The deposited zinc particles form a dense protective coating.
The zinc coating provides:
- Resistance against atmospheric corrosion
- Protection from moisture and salt exposure
- Sacrificial protection for steel
- Extended service life of metal structures
Compared with traditional painting systems, zinc thermal spray coatings provide long-term metallic protection for demanding industrial environments.
Applications
